Copper slag is generated during pyrometallurgical production of copper from copper ores containing materials like iron, alumina, calcium oxide and silica.

Despite its high iron content, this slag is currently disposed of in landfills, further processed as inert material, or used as an abrasive in industrial processes. However, this last option is not a sustainable solution, because the granules derived from the slag and used as an abrasive are themselves disposed of after re-use. However, because it is composed of iron oxides and silicates, the slag has semi-conductive and mild ferromagnetic properties and could be used to produce innovative advanced materials for heating applications, substituting materials with much higher embodied energy and bringing environmental benefits

Abstract

Copper slag is generated during pyrometallurgical production of copper from copper ores containing materials like iron, alumina, calcium oxide and silica. Every ton of metal production generates about 1,63 ton of slag [1] which dumping or disposal cause environmental and space problems [2,3,4]. Despite its high iron content, this slag is currently disposed of in landfills, further processed as inert material, or used as an abrasive in industrial processes. However, this last option is not a sustainable solution, because the granules derived from the slag and used as an abrasive are themselves disposed of after re-use. However, because it is composed of iron oxides and silicates, the slag has semi-conductive and mild ferromagnetic properties and could be used to produce innovative advanced materials for heating applications, substituting materials with much higher embodied energy and bringing environmental benefits
